To all whom concern: Be it known that 1,. SAMUEL B. VAN

RANST, of thecity of Syracuse, inthe county ofQnondaga and State of New York, have inventeda. certain new and useful Incandescent-Electric-Lamp Socket, of. which the following is a specification.

My mventionhas for its objectjthe production of a particularly simple vand effiporting incandescent electriclamps inplaces where there ,is vibration: and it consists Ain cientf'soeket, especially applicable for supthe combinations fand vconstructions herein-` titer set forth ndi'claimed.

deseribin f his"invention` reference is had 'to-fthe 'accompanying draw'ving in .which like .characters -designate corresponding', parts in all, the views. l Figure 1 is a longitudinal sectional view of -my lamp socket.- Figs.f.2 .and 3 are, re-

spectively, atop plan and 'anginverted plan'- thereof. -Figi 4 1s an inverted -plan of the receptacles@ Big5 is a lan otthe base.

Figsi 6 and 7 are, respectively, detail yi'ews 251of'the-spring conductorsof the socket.

1 and 2 are, respectively, a base and--a receptacle mountedon Ythe base', said elements beingformed of insulation and'hav ing opposing 4surfaces 3', 4, and ione of s aid `elements as the .receptacle 2 having a mar-V ginalannular lange'' projecting toward the other element and together with 'said opposing surfaces'S, 4conining acha'mber 6. 7 is aterminal .for engaging one of the terminals of-a lamp, the terminal 7 being -the 4usual'screw threaded sleevehaving a flange 8 at its bottomwhich engages a ledge or other surfaceat the bottom ofthereceptacle and entends around acentral boss or for engaging the central terminalof the lamp, the opening 11 registering with a pas -56 sage 12 extending through the bottom of the receptacle and communicating with the chamber 6. l

- 13-and 14 are terminals mounted -on the i surface3 of the base within the chamber 6 and on opposite sides ofthe axis of the o socket, said terminals' 13, 14 being held to i specification ofteaersratent. Patented- ;ec, 27, 1910 Application led October 5, 1910. Serial N o. 585,468. v

Usually 'said terminals 13, 14 are countersunk in the uppersurface 3 ofthe baise. 24 is' a spring conductor located within the. chamber 6 between said opposing-surfaces 3, 4 of the base andthe receptacle, said conductor 24v being'. electrically 'connected tothe sleeve terminal 7' and to one of the wire terminals as the terminal 13 on such `terminals and frictinally engaged with the' other.A As here' shoavn, the spring v"conductor 24 Vis in the form ofla'loop (Fig. 7)' having one arm longer thanltheother and 'provided with an opening 25 in its longer "arm which v.receives one of the screws 10 which hold the sleeve terminal in position. Thel 'shorter armfricti'onally engages its Contact lpoint 26 with the wire terminal 13.

' 27 is a spring conductor'electrically connectd to' the'terminal 14 on the base and extending upwardlyT through the opening 12 of the receptacle and theopening'll in the the base and -:being usually fixedfto one of y sleeve terminal 7 into said sleeve terminal,

' and carrying a' terminal 28 at its end for engaging the central terminal of t-lie`lamp and making` electrical contact therewith when the lamp isbutpart way in the socket.

As here shown, this conductor 27 is a spring arm fixed 'at .one end direct-ly to the terminal 14 on the base. v

29 is a. fastening' member Aas a .screw or 9:

bolt for holding'the base and receptacle to-A gether, said'member being located centrally of the jsocket and extending -through the boss 9 andhavin its head arranged in a recess 30 in saidV times insulated from any of the conductors of the lamp.
